| 20090091600 | MICRO-FLUID EJECTION HEAD AND STRESS RELIEVED ORIFICE PLATE THEREFOR - A micro-fluid ejection head and methods for improving the fabrication and operation of the micro-fluid ejection head. The ejection head includes a photoimaged thick film layer attached to a substrate containing fluid ejection actuators. An orifice plate is laminated to the thick film layer. The orifice plate has a plurality of concentric orifices therein and is derived from a first photoresist material that is heated to a temperature sufficient to relieve film stresses in the photoresist material prior to exposing and developing the orifices in the orifice plate. | 04-09-2009 |
| 20090091604 | PROCESS FOR MAKING A MICRO-FLUID EJECTION HEAD STRUCTURE - A method of making a micro-fluid ejection head structure and micro-fluid ejection heads made by the method. The method includes applying a tantalum oxide layer to a surface of a fluid ejection actuator disposed on a device surface of a substrate so that the tantalum oxide layer is the topmost layer of a plurality of layers including a resistive layer, and a protective layer selected from a passivation layer, a cavitation layer, and a combination of a passivation layer and a cavitation layer. The tantalum oxide layer has a thickness (t) that satisfies an equation t=(¼*W/n), wherein W is a wavelength of radiation from a radiation source, and n is a refractive index of the tantalum oxide layer. A photoimageable layer is also applied to the substrate. The photoimageable layer is imaged with the radiation source and then developed. | 04-09-2009 |
| 20090185003 | HYDROPHOBIC NOZZLE PLATE STRUCTURES FOR MICRO-FLUID EJECTION HEADS - A nozzle plate for a micro-fluid ejection head, a method of making a hydrophobic nozzle plate, and a method for improving the resiliency of a nozzle plate. The nozzle has a photoimageable hydrophobic polycyclic polyolefin layer derived from an epoxy functionalized polynorbornene. | 07-23-2009 |
| 20090186293 | DRY FILM PROTORESIST FOR A MICRO-FLUID EJECTION HEAD AND METHOD THEREFOR - A method for making a dry film photoresist layer for a micro-fluid ejection head and a micro-fluid ejection head made by the method. The method includes applying a photoimageable liquid to a moving web of release material to provide a photoimageable layer on the release material using a slot die coater. The layer on the release material has a coating thickness ranging from about 8 to about 25 microns with a thickness variation of no more than about one micron. The photoimageable layer on the web is dried to provide a dry film photoresist layer. A protective web is then applied to the dry film photoresist layer. | 07-23-2009 |

| 20090126002 | SYSTEM AND METHOD FOR SAFEGUARDING AND PROCESSING CONFIDENTIAL INFORMATION - One aspect of the invention is a method for providing restricted access to confidential services without impacting the security of a network. The method includes using a gateway to isolate one or more components providing confidential services from one or more other portions of an enterprise network. A first communication directed to a selected one of the one or more components may be received at the gateway. A determination may be made as to whether the first communication is user traffic or management traffic. The first communication may then be authenticated. If the first communication is user traffic, the first communication is forwarded to a component providing the confidential services. If the first communication is management traffic, the first communication is encrypted and forwarded to a component providing the confidential services. Additionally, components of the sub-network may be monitored to identify malicious changes. | 05-14-2009 |

| 20110084015 | SUMP FILTER RESTRAINING DEVICE - A sump filter assembly for filtering hydraulic fluid supplied by a transmission sump includes a filter housing, a support member, a retainer member, and a biasing member. The filter housing has a top surface and a bottom surface, wherein the bottom surface opposes a bottom surface of the transmission sump. The support member includes a first end portion attached to the filter housing. The retainer member is slideably connected to the support member and includes a first end portion having a retaining surface, wherein the retaining surface opposes the top surface of the filter housing. The biasing member has a first end in contact with the retaining surface of the retainer member and a second end in contact with the top surface of the filter housing. | 04-14-2011 |
